On Christian Doctrine continues, as St. Augustine waxes eloquent over the eloquence of Biblical writers. He gives us a rhetorical analysis of one passage of St. Paul and another of the prophet Amos, and we also learn a bit about the ancient art of elocution. (Which would come in handy for us audiobook readers, it would seem.) We don’t tend to think of the Bible as an oral work deploying oral rhetorical skills; St. Augustine thinks that way of it first.
